Zero Based Staffing/Services (ZBS/S)--a management tool designed to portray the relationship between the people or staff of an agency and the services they perform--was used in this study to inventory library services and staffing at the Central State University Library and provide a long-range planning analysis for library and university administrators. Within this framework, the staffing and services of the following library departments are described: Reference, Circulation, Government Documents, Public Access, Archives, Acquisitions, Cataloging, Serials, and Personnel Services. An organizational chart of the library is provided, and the text is supplemented by various charts and diagrams. Information from selected Texas universities for comparison is appended, and an index is included. (EW)
